[U-Boot] u-boot-imx on Freescale MX28EVK

[Matthias Fuchs <matthias.fuchs@esd.eu>]

Hi Fabio,

thanks for your details. Some of the discrete switches where messed up.
Boot Mode was fine. So now it's working fine.

Even the power button is not needed ;-)

I still have to investigate a little to get USB recovery working. This
does not work out of the box as with Freescale'S initial 2009.08 u-boot
for this CPU.
